I am extremely normal about this game and about Noah (jump cut to me losing my mind in a good way). I love the dialogue so much, the way he sounds like a tired introvert who just wants to sleep in the privacy of his own room but MC keeps knocking on the door, trying to talk to him and get inside. I also like that you made the dialogue smaller to show that he's mumbling to himself. I love that he always sounds quiet; even when he gets mad and his font goes into boldface, it never feels like he raises his voice, which is just *chef's kiss* so cool.
I love how you show his emotions through subtle shifts in his facial expressions. Literally just lowering his eyebrows makes him feel so menacing because it feels like he's very careful at controlling his expressions, which makes me feel that he's a lot angrier than he looks. Oh my gosh, and the CG where he's standing over you, head tilted, right shoulder slightly up is SO menacing.
Oh oh, and that sound effect of his bedroom door opening sent chills up my spine every time!
I have some questions about the full game, but I'll ask them on your Tumblr since that's where you asked to have them sent. (I would also love to draw some fanart for you if I can get around to it lol.)
All this to say, you did a fantastic job at characterizing Noah, at making this world so immersive, and at setting up the foundation for so many fascinating mysteries. Thank you for making such a delicious yandere game.
